Problems solved by technology

Among them, the main component of silicate inorganic fireproof adhesive is sodium silicate, so its water resistance is poor and its adhesion is small; while the composition of general polymer organic fireproof adhesive is complicated, which leads to cumbersome process and high production cost.
Since the silicate inorganic fireproof adhesive has a small expansion coefficient when heated, and the polymer organic fireproof adhesive is seriously carbonized and decomposed when heated, it has no filling effect on the gap left in the process of bonding the door core board, so their fireproof performance and poor thermal insulation

Abstract

The invention discloses an intumescent fireproof glue for fireproof doors and a preparation method thereof, relates to the field of fireproof materials, and comprises the following raw materials in parts: 65~75 parts of rubber, 55~65 parts of flame retardant microcapsules, liquid silicon 50~53 parts of sodium bicarbonate, 47~49 parts of expanded graphite, 40~45 parts of glycerin, 36~38 parts of spherical closed-cell expanded perlite, 30~35 parts of hypophosphite, 15~20 parts of additives and 45~ 65 servings. The invention is easy to construct, and can expand violently under flame or high temperature to form a fire-resistant and heat-insulating layer to prevent flame and smoke from spreading and achieve ideal fireproof performance.

Description

technical field [0001] The invention relates to the field of fireproof materials, in particular to an intumescent fireproof adhesive for fireproof doors and a preparation method thereof. Background technique [0002] At present, the adhesives used in the fire door industry mainly fall into the following two categories: silicate inorganic fireproof adhesives and polymer organic fireproof adhesives. Among them, the main component of silicate inorganic fireproof adhesive is sodium silicate, so its water resistance is poor and its adhesion is small; while the composition of general polymer organic fireproof adhesive is complicated, which leads to cumbersome process and high production cost. Since the silicate inorganic fireproof adhesive has a small expansion coefficient when heated, and the polymer organic fireproof adhesive is severely carbonized and decomposed when heated, it has no filling effect on the gap left in the process of bonding the door core board, so their firepro...
